A monitoring and protection circuit associated with a voltage regulator supplying power to a CMOS circuit device can sense over current levels precisely enough for determining if a fault has occurred, e.g., latch-up, failed or shorted transistor, etc., then this monitoring and protection circuit may automatically generate a fault alert signal and/or cycle power to the CMOS circuit device when an unexpected over current may occur, e.g., CMOS circuit latch-up. The monitoring and protection circuit may be integrated with a voltage regulator, e.g., low drop-out (LDO) voltage regulator. The monitoring and protection circuit may be integrated with a CMOS circuit device, e.g., digital processor. The monitoring and protection circuit may be a stand alone device. |
